A Costa Rican turkey for #BirdOfTheDay #stripes

One of these flew into the picture window of our casita, bounced into our hot tub, and died as we watched. It was pretty traumatizing. 😭

Hopefully, I'll learn how to take better bird photos.

Good morning/ afternoon/ evening. Today’s #BirdOfTheDay theme is #stripes any bird that has a stripe marking. The alternative is #mono bird captures, black and white. Good luck. #birds #photography #EastCoastKin

It's #RockinTuesday. Here's just a short segment of the trail to #Angel'sLanding in #ZionNP. Although this was taken many years ago, the trail remains the same, steep and hazardous. The view from the top is unsurpassed.

For #BirdOfTheDay, the theme is #stripes. Here's a pair of White Fronted Bee Eaters from the Lufupa River in #Zambia. #BirdPhotography #photography #Africa

One more for the #BirdOfTheDay theme of #Stripes Hope you all enjoy your day wherever you are in the world. Take care and see you soon. Remember to support each other. Get on the BOTD feed, like a few and repost if you admire the capture. It’s a community. 😊 #birds #photography #EastCoastKin

Just saw this raft of sea otters in Morro Bay this morning. And several of them have pups. #SeaOtters #MorroBay #photography #WestCoastKin #WildlifePhotography

Taken last week at the lake. It was a very cold wait for the sun to appear but it was worth it. 🧡💛

For #Stunday, thought I'd share a sequence of shots showing some of the big waves we've had recently along the #WestCoast. This is the #MorroBay breakwater, ranging between 15-20 feet tall. The light beacon in the first image is 36 feet tall. #BigWaves #PacificCoast #photography

It's a lazy Saturday. At least it is for this #Panda in #Chengdu, #China.

This is a beautiful red-shouldered hawk. As I was photographing a night heron, I noticed this beauty standing in the snag above it. I didn't see it until it made its loud shrieking cry. I mashed the shutter when it looked at me. #photography #wildlife #wildlifephotography #EastCoastKin #birds #hawks

It's #Stunday. Just back from a trip to #Sicily, here's a photo of #MtEtna wearing what appears to be a white lace neck collar. It's actually snow from a recent early winter storm. Taken from the Greek/Roman theater in #Taormina, #Sicily. #photography #LandscapePhotography #travel #Italy

This may not be stunning, but it is very interesting. A stone placard dated 1862 showing how long a meter is, as well as centimeters. In addition there are two other measurements; A 'Palmo' and a 'Canna', both defined in terms of meters and/or centimeters. Taken in #Ragusa. #Sicily. #photography

This is Cosmo. Cosmo's job is to navigate the narrow streets (too narrow for vehicles) of Castelbuono, Sicily collecting trash and recyclables from the houses. He carries these materials in two wooden boxes on his back, boxes made by local high school students. #photography #Sicily #Castelbuono

It’s #Stunday and I’m traveling in #Sicily. Here’s a shot of the Temple of Concordia. One of the most complete Greek era temples in the world. A beautiful day and very few people. #GreekArchitecture #photography #PhotographersOfBlueSky
